Abstract

L'invention concerne un coffret de commande, par exemple une armoire de commande à corps de coffret présentant, dans la zone d'une paroi latérale (10), un système de climatisation pourvu d'un échangeur thermique (20) sur lequel est fixé au moins un ventilateur (33) qui achemine l'air de l'intérieur du coffret de commande dans des conduits de ventilation internes (28, 2) de l'échangeur thermique. L'invention vise à réaliser un coffret de commande de structure simple permettant simultanément un dimensionnement sur différentes puissances de refroidissement. A cet effet, l'échangeur thermique est réalisé sous forme d'échangeur thermique air-air comportant des conduits de ventilation externes (28, 1) séparés dans l'espace des conduits de ventilation internes (28, 2) et il présente, dans la zone des extrémités du côté long des conduits de ventilation externes et internes, des segments d'extrémité auxquels on peut fixer des coffrets de prolongement (30) sur lesquels sont maintenus les ventilateurs (33).
